One important reason is that the English language has a wide range of words for substitution, unlike Ancient Chinese and Modern Chinese. In Ancient Chinese, for example, we don't(I don't use DIDN'T) have many pronouns; and when it comes to anaphora, we simply repeat it. But there is something worth mentioning: I once read a guide and the writer says he frowns when he sees some writers make their essays full of pronouns. There are some style guide writers who consider it bad to use pronouns frequently.
